' yMy invention is a clutch for line shafting to form a clutch connection between the ends oitwo adjoining rotatingshafts. The

clutch is oiy thel rigid type and is not intended to accommodate a flexibility of the shafts or misalignment thereof.

An object ofmy invention. is aline shaft .clutch for i'orclngthe grip of the clutch.

in alignment .atten a ffulli Vgripv has; been` more specific V'objectof my invention is ina clutchhaving a splitsleeve/and press-4 K ingonepart `of the sleevepositively againstl the shaftbefore the-other-part of the` split sleeveis givenfa movementto `grip the shaft,

"thereby preventing afmisealignme'nt of the shafts, thezhousing and gripping elements being. mounted on the shaft opposite to the one having the sleeve .thereon;'f:.

In yconStructing my invention I utilize certain-standardeaturesiin which one of the Y shafts has asliding cone-actuated .by the' Y usualclutch'lever. and alsolias. a `fixed VcollarV onthe yend ofsuchy shaft, the clutch housing' being l'rigidly.connected'to the collar, the

In the drawings, the porveirsliaft l is to drive the driven shaft 2 by means of a clutch arrangement secured to theends 3 in the direction of vthe Vand trespectively of such shafts. A clamp-,- 'ing collar 5 is secured on the lpovve'r shaft spaced from theend andj a split sleeve G .is fitted on the end` of such power shaft; such sleeve isv illustrated particularly *inv Figurev 4', and has' al plurality of partial Vlongitudinal slits" 7 and'l 8 and partial circumferential'slits 9' and llO.; A squarelug'.

6. A clutch for alivned shaftscomprising in combination a clutch collary having a housing, a plurality of levers pivotally connected to the housing, a sleeve split so as to form a solid portion and two resilient portions at either end of the same, a compression lug connected to one `of said resilient portions and a cam lug connected to p the other resilient portion of said sleeve,

means associated with one of said levers for depressing said compression lug and 'caus- `ing oneofl said Aresilient portions to engage one ofL said shafts, cam means on the other of said levers, permitting said cam lug to depress the other resilient portion of said sleeve to engage saidshaft, `the lever operatn ing saidk compression lug being longer than the lever operating said cam lug,a,nd a sliding cone on the other of sai-d shafts adapted to engage the ends of said :levers` to operate the same` whereby said first mentioned lever will be operated first.

A clutch for aligned shafts comprising in combination a clutch collar having a housing, a plurality 4of levers pivotally connected to the housing, a sleeve split so as to form a solid portion and two resilient portions, a compression lug yconnected to one of said resilient portions and a cam for actuating saidrlevers, said lever which Y operates said compression lug` being adapted to be operated first. f Y

In testimony whereof I have signed .my
